2. TissueGroup of cells that performs unified functions.
Epithelial Tissues
Connective and Supportive Tissues
Vascular Tissues
Muscular Tissue
Nervous Tissues

3. Epithelial Tissue
•For protection.
•Simple vs. Stratified (name of the strata
depends on the topmost layer.

4. Simple Squamous
• Covering of the blood vessels

5. Simple Columnar
• Lining of the digestive tract

6. Simple Cuboidal

7. Pseudostratified

perform secretions.

Glands

15. Connective Tissue•Fewer cells and large amount of matrices
(space).
• connect one tissue to another and join
organs which are attached to the backbone
•Example: Ligaments (connects bone to bone)
and tendons (connect muscle to bone)

16. Connective TissuesComponents: Fibers, Inorganic and Organic Substances
FIBERS Inorganic substances Organic substances
1. Elastic Fibers (Yellow) – thin,
straight and branching
2. Collagenous Fibers (White) –
thick, wavy and non
branching
3. Reticular Fibers – short and
multi-branching.
1. Calcium
Carbonate
(CaCO3)
2. Calcium
Phosphate
Ca3(PO4)2
1. Collagen
2.Mucopolysaccharide
(glycosaminoglycans)

17. Types of Connective Tissue
1. Elastic Connective Tissue
found in ligaments
(more elastic than
tendon)

18. Types of Connective Tissue
2. Fibrous Connective Tissue
wavy and made up
of collagen.
Ex: in tendon

19. Types of Connective Tissue
3. Reticular Connective Tissue
- Network of reticular
fibers that can be
found in spleen, lymph
nodes and bone
marrow.

20. Types of Connective Tissue
4. Areolar Connective Tissue
it has two fibers
(thick collagenous
& elastic fibers)
-found in dermis of
the skin and
mesentery ex:
Pericardial cavity

21. Types of Connective Tissue
5. Adipose Connective Tissue
it is found on
subcutaneous layer of
skin; it also protects the
mammary glands and
storage of foods.

22. Supportive Tissue1. Cartilage – allows movements and keeps the
tubes open at all times.
2. Bones – made up of Haversian System

23. Supportive TissueHyaline Cartilage Elastic Cartilage Fibrocartilage
- has no fiber; purely
chondrocytes
- present in nose and
fontanels of babies
during embryonic and
early stages. (weakest
cartilage)
- is a yellowish
flexible cartilage
made up of elastic
fibers.
- found in external
ears, epiglottis and
larynx.
is found in
intervertebral
discs, joint
capsules,
ligaments.

24. Hyaline Cartilage

25. Elastic Cartilage

26. Fibrocartilage

27. Bones Haversian system is composed of
the following;
1. Haversian canal (central
canal) contains blood vessels
such as capillaries.
2. Haversian laminae (matrix) –
gives protection
3. Osteocytes – bone cell which
secretes materials like
Calcium carbonate
4. Canaliculi (small canal) forms
connections like nerves
5. Periosteum – membrane of
bone cell which is designed
for protection.

30. Vascular Tissue
Plasma – mainly fluid (composed of
90-95% water) and others are
organic and inorganic
compounds.
Its main function is to transport materials throughout the body.

31. Vascular
Tissues
Blood - generally transport materials in the
body. It is a liquid tissue because it is
composed of different cells like Red blood cells
(RBC)/Erythrocyte, White Blood cells
(WBC)/Leukocytes and Blood platelets
(Thrombocytes). It has large amount of water
(H2 O), making it as fluid. It also contains
organic compound like sugar (dextrose, liquid
form of glucose) and proteins
Lymph - for drainage, replaces whatever less from
the blood/circulatory system, and for building
immune system and resistant to diseases.

33. Albumin  binds water, cations (such as Ca2+, Na+ and K+),
fatty acids, and hormones. It also regulates the
colloidal osmotic pressure of blood.
Fibrinogen  for blood clotting and blood coagulation. It is
transformed into fibrin
Globulin  (Alpha and beta globulin – maintains viscosity of
the blood while Gamma or Immunoglobulin (Ig’s)
for immune system.
Component of Plasma

34. Red Blood cell- Looses it nucleus upon maturity
resulting to biconcave-shaped.
Its shape provides larger surface
are for binding oxygen from
environment and transport it to
body tissues.
- It contains Hemoglobin, an iron-containing protein which
makes blood red in color.
- Reticulocytes are immature erythrocytes

35. White blood cell

36. Mechanisms of Immune System

37. Mechanisms of Immune System

38. Muscular TissueMain Function: for contraction leads to locomotion.
1. Excitability – capacity to receive and response
to a stimulus.
2. Contractility – the ability to contract or shorten
3. Extensibility – ability to stretch.
4. Elasticity – ability to return to its original shape
after being stretched or contracted.

39. Types of Muscles

41. Nervous Tissues

42. Nervous Tissues

43. Kinds of Neurons
Sensory / Afferent Neuron – transmit impulses from
receptors (parts that receive stimuli) to Central
Nervous System (CNS).
Associating / Interneuron – transmits impulses
from sensory to motor neurons (within CNS)
Motor / Efferent Neuron – transmits impulses from
CNS to effectors (parts that exhibits response or
reaction to stimuli).

44. Kinds of Nerve FibersMyelinated – covered with myelin sheath, an adipose tissue which
protects nerve fibers.
Non-myelinated – does not covered by myelin sheath

45. Gray Matter – non myelinated
(important in decision making)
White Matter – myelinated (important in
immediate response)
Reflexes that require immediate
response is processed in spinal cord.

47. Types of Neural Circuit

48. 1.Convergent – impulses coming from
different sources moves in the same neurons

49. 2. Divergent – impulses moves either in the same or
multiple pathways in transmitted in different neurons.

50. 3. Oscillation/Reverberation – it is the
circumnavigation of impulses among neurons.

51. 4. Parallel after-discharge – consists both of convergent
and divergent circuit. It involves during complex mental
processes.
